LOCKING- DEVICE FOR MAIL-*CH'UTES.

Specification of Letters Patent.

Patented March 1Q, 1905.

Application filed January 6, 1906, Serial No. 294324;. Renewed November4:, 1907. Serial No. ceases.

To. all whom it may concern:

Be it known that l, Josnrn WARREN OUT- LER, of Rochester, in the countyof Monroeconstructed to extend through the floors of a I building to acollection receptacle for facilitating the collection of postal matterfrom a building, and the object of the present invention is to providean improved locking device adapted to beapplied to a base section, orother part of the chute, whereby such part or parts may be locked inplace under normal conditions, but which, when necessary, may be quicklyunldbked and removed to render the interior or other portions of thechute accessible.

To these and other ends the invention. consists in certain improvementsand combinations of parts all as will be hereinafter more fullyexplained, the novel features being pointed out in the claims at the endof the specification.

In the drawing :-Figure 1 represents a vertical section through aportion of a chute and a base section, constructed in accordance with myinvention, and Figs. 2 and 3 are perspective views of the upper andlower members respectively of the base section for the chute.

Similar parts in the several. views are desigiloor section and theadjacent parts of the ch te 1n the present embodiment y inven tion 1designates a section of the chute above the llOOI 2, a bracket eelsecured to J ',"i 1. i '.1. suitable caching e and provided t l suitablemeans for fastening the attaching flange 5 ohhaving an upward extension12 having an apertured staple 13 projecting forwardly therefrom. Theupper member 14 of the base section is adapted to be supported by thelower member and conforms generally to the outline of the frame, and itcomprises a frame having a front and two sides, the rear thereof beingopen to enable it to be fitted against the chute while the latter is inposition, the lower front edge of the upper memher being provided withone or'more projections 15 arranged to engage at the rear of thecorresponding part of lower member 9. An aperture 16 is formed at theproper point in the front of the upper member to receive theforwardly-projecting staple 13 on the lower member, and as theprojections 15 of theupper member are engaged with the lower member andthe upper member is then tilted rearwardly against the verticaleXtension 12, the staple 13 will pass through the aperture 16 of theupper member and pro ject through to the front surface thereof, and bypassing abolt or how of a lock 17 through the aperture of the staple,the upper memher will be firml locked to the lower member. As the lowerase member 9 is fixed po sition by securing devices 11 which arepreferably located within the base, it will be impossible forunauthorized persons re move it, as it will be necessary UlllUCl-Iremove the upper member iii-order l9 this, and as the floor section thec and also the securing devices for and adjacent sections of the ifclosed and concealed by base secti when its in locked position, a d asthe loch is controlled by a key o l l A po protec rev tn (lb-Wally L "11 a I tamper i in ear lei ence M- a. "J y by un utnoria M meansembodying my present invention is not only adapted to the base sections,but is also applicable to other parts of the chute, such for instance asthe securing or supporting devices for holding or locking the chutesections inposition. to prevent their removal or opening, and thepresent invention provides efl'ective means for locking the chute andthus prevents unauthorized access thereto, as the staple or part adaptedto receive the lock is secured by screws or equivalent securing deviceswhich are concealed or inaccessible when the parts are in lockedposition, and hence all of the parts are under control of the look.

I claim as my invention:

1. The combination with a mail chute, of a base section thereforembodying a removable member, and a locking device for the said member.

2. The combination with a mail chute, of a base section for protecting aportion of the chute, embodying a relatively fixed memher, a movablemember, and a locking device for controlling relatlve movement of themovable and fixed members.

3.
